To ail may concern? Be it knowntha't 1 'GHA'RLES newiand' useful Improvements in Spring- Tires ain'd'l do hereby declare tlie following to be: full, clea-r, a'nd exact descriptloir spring tires andhas for one' of its-objects the'pr'ovision of a deviceof this character whereby su'lhcient resiliency willbe furnished by the materi'aLOf -the tire when passing over a comparatively even surface and which tire is capable of moving inwardly under tension ineans when engaging obstruc tions such as ruts or stones on the surface of the roadway so that the shocks and jars are absorbed thereby.

Another object of this invention is the provision of a rim construction removably secured to the felly of a wheel and having tire supporting means carrying tire sections and cushionly supported so that they may move inwardly when the tire sections engage obstructions thereby absorbing the shocks and jars to the wheels.

A further object of this invention is the provision of a spring tire'of the above stated character, which shall be simple, durable and eflicient, and which may be manufactured and sold at a comparatively low cost.

With these and other objects in view as v will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my in vention, reference is to be had to the following description, and accompanying drawings, in which: I

Figure 1 is a front elevation of a spring tire constructed in accordance with my invention,

Fig. 2 is a fragmentary plan View illustrating the sectional tire,

Fig. 3 is a fragmentary vertical sectional view illustrating the manner of cushionly supporting the tire supporting means.

tiona'l view illustrating the manner ofsecuring the rim structure to the felly of the wheel,-a-nd" Fig. 5 is a fragmentary plan view illustrating-the mean's of connecting the inner and outer rims.

.R-eferrin'g in detail to the drawing, the

numeral 1 indicates a hub having secured theretoradial spokes 2 on which ismountedthe folly 3. -The felly 3 carries a rim 45'- having formedilpon' one edge a retaining flange 5*:and has its other edge cooperating with a removable flange 6. The removable flange 6 is secured to the felly 3*by means ofbolts 7. The aforedescribed construction relatesto a we1l' known type of wheel and to' which m-y invention is applied.

A rnn construction 8 consists of inner and outer rims 9 and 10 which are secured to- 'gether" by bars or members 11.

The bars or members 11 are seated within recesses formed within the rims 9 and 10 for preventing the rims from having relative movement in relation to each other when the bars or members are secured in place. The inner rim 9 is positioned upon the rim 4 and held thereon by the removable flange 6 as illustrated in Fig. 4:. The outer rim 10 is provided with a plurality of spaced rectangular openings 12 to slidably receive stems 13 formed upon the tread supporting members 14. The tread supporting members 14 have formed thereon tread engaging flanges 15 which secure thereto tread sections 16 constructed of rubber or any other material suitable for the purpose. The tread sections 16 are located in close relation to each other so as to form a substantially continuous tread to the device but are spaced sufficiently to permit the members 14 'to move inwardly when their respective tread sections 16 engage an obstruction.

Lugs 17' are formed upon the outer face of the inner rim 9 and arranged in spaced relation and in alinement with the rec tangular openings 12 and have secured thereto the inner ends of coil springs 18. The outer ends of the coil springs have formed thereon screw threaded extensions 19 that are threaded into the stems 13 to establish a connection between the springs and the tread sections. The springs are of such a strength that they normally support the members 14 in spaced relation to the outer rim 10 when under the normal weight of thef'automobile or vehicle and the ma pants thereof but which permit the members 14: and tread sections 16 to move inwardly when engaging an obstruction to absorb theshocks and jars therefrom.

A protector 2O surrounds or is mounted upon each of the springs 18 and is interposed between the inner and outer rims 9 While I have shown, and described the preferred embodiment of my invention,-it; will be understood that minor changes in construction, combination, and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

What'I claim as new 1s 1, A spring tire comprising inner and outer rlms, members securing said rlms in spaced relation, means securing the inner Copies of this patent may be obtained for rim to the felly gof a wheel, said outer rim having rectangular openings, rectangular stems slidable in said openings, tread sup- "porting' members formed upon said stems,
